And as detailed in a new paper, published in The Planetary Science Journal last month, they found something surprising down there: Jupiter appears to contain one-and-a-half times as much oxygen as the Sun — far more than previous estimates, which suggested it was only a third as much oxygen.
Their model suggests that gases move far more slowly through Jupiter’s atmosphere than previously thought.
“Our model suggests the diffusion would have to be 35 to 40 times slower compared to what the standard assumption has been,” Yang explained. “Instead of moving through an atmospheric layer in hours, a single molecule might take several weeks.”
